• Reduce rendering overhead in very long conversations during response streaming, interface layout, and navigation previews by @imccyu

Chores

• Enable web_fetch by default for the Python SDK, Headless, ACP, and custom Profiles by @koalazf99
• Stop exposing the general-purpose workflow tool by default in Web PTC Mode by @koalazf99
• Replace Session.events with on-demand read APIs: seq, eventAt(), and snapshotEvents() by @kermanx
• Distinguish SessionSeq and SessionLogOffset with strong types; developers should should pay attention to compatibility by @tianyicui
